Web Apps


We build modern web applications of all shapes and sizes using the latest technologies.

Our experienced team has over 30 years of combined web app development experience. From online marketplaces and platforms to SaaS solutions, custom business software, and chrome extensions. Whatever your idea, we can build it, on time and on budget.

Mobile Apps


Our unique mobile app development process allows us to rapidly build cross-platform apps at a fraction of the cost.

We build mobile apps using React Native, a revolutionary framework built by Facebook in 2015. React Native allows us to build iOS and Android apps using just one code base (instead of two). This reduces the time and cost to build cross-platform apps by 50% or more, without sacrificing speed or quality.

Custom Software


We build custom software applications tailored to your business.

Outgrowing your off-the-shelf software? We’re here to help. From custom CRM’s and accounting systems, to project management and billing solutions... custom software consulting is our specialty.

UI / UX Design


We design and build beautiful apps that the users love.

Our detailed, proven design & build process ensures that we build the right features for your app. To build digital experiences, we use the Material Design spec, the only proven design specification for the web, backed by Google.

Some of Our Work

  • Uber iPhone app multiple views of the app.
  • Uber iPhone app chat view.


Two years ago, Uber’s corporate chat application began to fail due to their company’s massive growth. Uber’s engineering team was tasked with building a new, custom chat app with web, desktop, and mobile clients. For mobile, they decided to use React Native, but they didn’t have the in-house resources for the project so they elected to hire a third-party vendor that specialized in React Native. After considering their options, they selected FullStack Labs to lead the development of the React Native iOS and Android apps for uChat, both of which are currently live and being used across the organization by tens of thousands of Uber employees.

We were very happy with the way the whole process was facilitated. We started talking to FullStack Labs three months before we signed any contract with them. We met with them in person several times. We wanted to find out what their philosophy is. Both Brian and David are fathers with young children, so they understand the importance of the work we are doing. That shows through in their work. It was obvious they cared deeply. David even put in $25 into our crowdfunding campaign. It's a business relationship, but he cares about our success, which is rare. It's not just about the product, but the bigger mission, too.

The experience I've had with other firms is in direct contrast to what FullStack did. I'm comparing them with two other firms I worked with in the past. They care a lot about what their clients are doing. They bring their ideas and concepts to the table. I felt like they were on my team. They added a lot of value in terms of ideas and continue to do so. No matter who's working on the project you feel like they care about the work that's being produced.

FullStack Labs' managers have been engaged throughout. The whole project management staffing, matching team to task has been fantastic. All their staff is very committed. I'm very aware of how much bureaucracy there is in the tech world, and we've gotten nothing but solutions. I am totally happy with their approach to everything, their integrity, honesty, the whole thing. It's great.
